The VTG 200 (above) provides six sets of video output connectors; the VTG 150 (at right) provides four sets. Each connector is marked for its video application.

See the table of video scan formats on page 4-1 and choose the one to be used to simulate your computer. Then connect the appropriate cables to the device to be tested. (e.g. projector, switcher, etc.)

15-Pin HD (VGA/XGA) Output

One connector is provided for the VGA/ XGA because the pin configurations are

identical. All scan rate signals go to the

VGA/XGA (15-pin HD), Apple/MacII/Quadra (15-pin) and BNC connectors. The BNC output is individually buffered, allowing devices to be connected to BNC and VGA/XGA outputs at the same time. However, because the VGA/XGA and Apple/ MacII/Quadra outputs are in parallel, they should not be connected at the same time.

_ If devices are connected to both 15-pin outputs VGA/XGA & Apple/MacII/Quadra simultaneously, the double termination will result in a loss of brightness.

The pin assignments for the 15-pin HD are as follows:

Pin 1 = Red		Pin 8 = Blue Ground
Pin 2	= Green	Pin 10	= Ground
Pin 3	= Blue	Pin 13 = H. Sync
Pin 6	= Red Ground	Pin 14	= V. Sync
Pin 7	= Green Ground

The sync available on pins 13 and 14 is dependent on the position of the H/HV switch. With the switch in the HV (down) position, composite sync is available on pin 13. With the switch in the H (up) position, separate H and V sync is available on pins 13 and 14.

15-Pin Apple/Mac II (VTG 150), MacII/Quadra (VTG 200) Output

All scan rate signals go to the VGA/ XGA (15-pin HD), Apple/MacII/

Quadra (15-pin) and BNC

connectors. The BNC output is individually buffered, allowing devices to be connected to BNC and Apple/MacII/Quadra outputs at the same time. However, because the VGA/XGA and Apple/MacII/Quadra outputs are in parallel, they should not be connected at the same time.

_ If devices are connected to both 15-pin outputs (VGA/XGA & Apple/MacII/Quadra) simultaneously, the double termination will result in a loss of brightness.

The pin assignments for the Apple/MacII/Quadra connector are as follows:

Pin 1 = Red Ground		Pin 9 = Blue
Pin 2	= Red	Pin 11	= C/V Sync Ground
Pin 3 = Composite Sync		Pin 12	= V. Sync
Pin 5	= Green	Pin 13 = Blue Ground
Pin 6	= Green Ground	Pin 14	= H. Ground
		Pin 15	= H. Sync

9 Pin, TTL Output

A 9 pin “D” style connector provides all TTL signal outputs. These outputs may

be selected from the TTL Scan Rates menu.

Pin 1	= Ground	Pin 5 = Blue
Pin 2 = Red Intensity		Pin 6	= Green Intensity
Pin 3	= Red	Pin 7	= Blue Intensity
Pin 4	= Green	Pin 8 = H. Sync
		Pin 9 = V. Sync

_ When running TTL rates from outputs other than the 9-pin TTL output, the test patterns may appear dim, distorted or otherwise unlike the output from the 9 pin connector. This is normal, due to the signal characteristics of TTL video signals. Thus, for exact TTL signal duplication, only use the 9 pin TTL output.
